Title: Improvements relating to countercurrent extraction apparatus
IPC: B01D11/04
Filed: 1950-08-23
Abstract: <PICT:0714056/III/1> Apparatus for the counter-current extraction of a liquid mixture by means of a selective solvent, particularly for the separation of undesirable constituents from lubricating oil base stocks, consists of a vertical column comprising mixing zones alternating with settling zones free from packing material, means for passing the mixture resulting from each mixing zone in a divided stream to an inner intermediate zone in each adjacent settling zone, and means for directing the mixture outwardly from said inner zones and allow separation into comparatively heavy and light fractions which pass around the said inner zones to the upper and lower adjacent mixing zones respectively.  As shown diagramatically in Fig. 11, a column 10 is divided into mixing zones 11 and settling zones 12 by means of annular gauge discs 13.  Upper and lower tubes 14 are located in each settling zone being secured to the disc 13.  A rotor shaft 16 passes radially through the column. Double conical baffles 17 are secured to the shaft and are located between the pairs of tubes 14.  Rotors 18 are also secured to the shaft and are located centrally in the mixing zones 11.  The upper tube 14 in each settling zone is preferably longer than the lower tube 14.  The external diameter of the baffle members 17 is preferably at least as great as the internal diameter of the tubes 14.  In using the apparatus for the extraction of mixtures of petroleum hydrocarbons, it is preferred to operate with the oil to be extracted as the continuous phase and the solvent as the dispersed phase, the oil being fed in at the base of the column and the solvent at the top.  According to Figs. 5 and 6 (not shown) the tower is provided with settling chambers at each end, and means are provided for supplying the liquid mixture to the lowest mixing zone and for supplying selective solvent to the top settling zone.

Title: Improvements in the manufacture of collapsible containers for plastic or fluid substances and apparatus for use therein
IPC: B21D51/36
Filed: 1936-07-28
Abstract: 479,037. Making collapsable tubes ; corrugating. DAVIS, C. July 28, 1936, No. 20900. [Classes 83 (ii) and 83 (iv)] [Also in Group XVII] An axially collapsable container for fluid, semi-fluid, or pasty substances comprises a tubular container of metal such as lead, tin, or aluminium, provided with pleats of V-shape, which pleats extend outwardly relatively to the tube in which they are formed. A tube 1, Fig. 1, is supported within a dio comprising sections 4 with its conical end resting in a corresponding recess in a plate 6 and its upper end sealed by a plunger 9. Compressed air under light pressure is admitted through the nozzle 3 to form shallow corrugations 10 in the tube wall, and the die sections 4, Fig. 2, are contracted axially, the plunger 9 following their movement, to complete the shaping, the production of sharp corrugations being assisted by the increase in pressure which occurs in this contraction. The compressed air may be replaced by the material which is ultimately to fill the tube, the plunger 9 being first lowered to expel air from the tube, and the tube then being filled and corrugated in the same operation. The substance is forced into the tube from a cylinder 35, Fig. 6, by a piston 36, the higher pressure being limited by a weighted 'plunger 31. Each plate 4 comprises sections 12, 13, Fig. 4, pivotally connected to a third section 11. The sections 12, 13 are closed during the operation by a common rod 15 which is removed to allow the sections to swing apart for removal of the finished tube. The plates 4 are normally held apart by springs 21, Fig. 5, to a distance determined by stops 22, 23, or the upper plate 7 only may be raised by springs, the other plates being spaced by the stops. The rotation of a screwed shaft 25 causes downward movement of the plunger 9, and, through distance sleeves 28, contraction of the die plates. The pressure fluid may, alternatively, be introduced through a duct in the plunger. The filled tube is closed by a base 39, Fig. 8.
